English doesn't have an accusative or dative case. There are a few different names for the two different cases of English pronouns; "nominative" (I/he/she) vs. "oblique" (me/him/her) and "subjective" vs. "objective" are both reasonably common.

From Wikipedia:

> An objective case is marked on the English personal pronouns and as such serves the role of the accusative and dative cases that other Indo-European languages employ.
